Oh, for pete's sake. Take a systematic approach, as Andreas suggested.
First, arrange for the filenames you want to be delimited by newlines.
Since this is for your own use, and you can more-or-less guarantee that
there will never be a newline in a filename, that's sufficient. Second,
arrange things so that the shell won't split words on anything but
newline, your desired delimiter.
Take a look at the approach in the following example script. `recho' is
part of the bash distribution; it's built while running the test suite.
I used `ls -1' to create a newline-delimited list of filenames.
$ cat x3
[ -d scratch ] || mkdir scratch
cd scratch
touch 'a b w' 'c d x' 'e f y' 'g h z'
IFS=$'\n'
recho $(ls -1 *)
$ ../bash-3.2/bash ./x3
argv[1] = <a b w>
argv[2] = <c d x>
argv[3] = <e f y>
argv[4] = <g h z>
